1.2A Peak, 6V, 3.5MHz Synchronous Step-Down Switcher Evaluation Board
The EV2160-QH-00A is used for demonstrating the performance of MPS’s MP2160, a low voltage high switching frequency step-down switcher with built in power MOSFETs. MP2160 provides up to 1.2A peak highly efficient output with constant-on-time control for fast loop response.
MP2160 is ideal for powering portable equipment that runs from a single cell Lithium-ion (Li+)Battery. The output voltage can be regulated as low as 0.6V.
High power efficiency over a wide load range is achieved by scaling down the switching frequency at light load to reduce the switching related loss by constant on time control. Short circuit and thermal shutdown provides reliable, fault-tolerant operation.
MP2160 is available in QFN8 2.0x1.5mm package.

1.2A Peak, 6V, 3.5MHz, COT, Synchronous Step-Down Converter with PG in 2mmx1.5mm QFN
The MP2160 is a monolithic, step-down switch mode converter with built-in internal power MOSFETs. It achieves 1.2A of peak continuous output current from a 2.7V to 6V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. The constant-on-time control scheme provides fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.
The MP2160 is available in a small QFN98 (1.5mmx2.0mm) package, and requires a minimal number of readily available, standard external components. The MP2160 is ideal for a wide range of applications including high-performance DSPs, FPGAs, PDAs, portable instruments, and DVD drivers.
